Modified hop count tracking to use running average vs. max

In addition to the running average implementation, this update also
provides a few slight performance optimizations.  One of the primary
advantages to this algorythm is that it does not need to loop over
then entire array for each hop count update.  Also enhanced log_aldb_status
a bit to include the device name.

Insteon: Enhance HopCount, Change to Average of 10

A moving average of the last 20 hop_counts was a bit excessive and required 10 messages before a hop count would change.
Insteon_HopCount: Check Per Device Setting on All Calls to Default_Hop_Count

Moved per device setting outside of logic so that they are checked even if a hop_count is not passed.
